J.Lo: 'Abrams save was easy decision'

Jennifer Lopez has stood behind the judges' decision to allow Casey Abrams to continue his journey on American Idol.

The 19-year-old aspiring singer was saved by Lopez, Steve Tyler and Randy Jackson during last week's live results show after receiving the lowest number of the public's votes.

"We knew that it was kind of a radical decision because it was so early in the season, but to be quite honest... that is one decision that I haven't lost one ounce of sleep over," she explained during an interview with Ryan Seacrest on his KIIS-FM radio show.

"[Casey] is one of our most dynamic performers. He's so interesting and so talented. I know it's crazy, but we had to do it!"

Abrams has been plagued by health problems since entering the competition and has been taken to hospital on several occasions.
